ADJUSTING THE FRONT DERAILLEUR
The adjustment of the front derailleur
requires a lot of experience. The setting in
which the chain does not rub the front de-
railleur is extremely small, the cable operat-
ing the front derailleur can stretch leading to
impaired shifting.
• Tighten the cable using the adjusting screw
just as you would on the rear derailleur
• For optimal performance, align the front de-
railleur exactly parallel to the chainrings with
between 1 and 3 mm of clearance between
the derailleur and the largest chainring
• To adjust the starting position of the front
derailleur, loosen the Allen screw on the
front side 2 to 4 times.
• The cable stops of the front derailleur are set
up as described in the section rear derailleur
adjustment.
How to adjust the chain tensioner
• Shift to the smallest sprocket
• The distance between chain and tensioner
should be 1 – 2 mm.
• To adjust the chain tensioner, rst loosen
the nut at the lower derailleur jockey
wheel. Then loosen the bolt.
• Adjust the chain tensioner.
• It is important that rst the bolt is tight,
then the nut is screwed tightly against it.
• Shift to the biggest sprocket. The chain ten-
sioner must not touch the tire or the rim.
The Birdy city chain tensioner
The chain tensioner Shimano Alfine with
additional chain tensioner is used for this
model. Adjustment is as describe above.
TIP!
Adjust a bigger distance between
chain and tensioner if your Birdy
is equipped with Big Apple tires.
This prevents touching between
tensioner and tires while shifting
into the smallest gear.
